E . , M E M B E R A S H R A E he road to high performing buildings is paved with high expectations— but, ultimately, it is measured performance that shows how energy efﬁcient a building really is. As owners and managers of more than 8 million ft² of Class A ofﬁce space in midtown Manhattan, including the Condé Nast Building at 4 Times Square, The Durst Organization understands this concept well. From this perspective, we’ve experienced ﬁrsthand the all-too-common frustration of a building’s energy performance not meeting design expectations, particularly a new building’s energy savings projection that overstates actual performance. Across the high performing building industry, these unrealistic energy performance goals have come from (among other things) inadequate modeling practices, failure to include operations staff in goal setting or accurately communicate the design intent to the staff and lack of adequate budgets for commissioning, evaluation and ongoing benchmarking. As more actual energy performance data become available on high performing buildings, clearer and more realistic expectations will help to establish conﬁdence within the building design and construction industry about costs and savings. By providing some of our data, observations and experience working through design, construction and operation of high performing buildings, speciﬁcally using the 4 Times Square building as an example, we hope to encourage others to share actual energy performance operating results and lessons learned earlier, Winter 2008 Condé Nast Building at 4 Times Square. 30 HIGH PERFORMING BUILDINGS
